“…Additionally, catalyst displayed a good performance in methanol steam reforming (reaching up to 90% methanol conversion), which also resulted superior compared to a commercial stainless-steel fiber sintered felt (≈10% higher). Whereas the structure of commonly used metal foams for this catalytic process cannot be entirely controlled or reproduced, [183][184][185] the procedure proposed by Lei et al allows to obtain reproducible materials with a high exposed surface area for depositing the active phase.…”

Additive manufacturing (AM) presents a promising opportunity for the innovative design and production of structured catalytic materials. Given the critical role of catalysts in industrial catalytic processes, AM has the potential to contribute to the development of improved catalysts by reducing activation energy and enhancing selectivity. Conventional synthesis methods limit the choice of structural materials and composition for producing monoliths. Additionally, the deposition of catalytic compounds is also restricted by commonly applied techniques that may require prior coverage or treatments to improve adherence or do not achieve a homogenous coat. Moreover, production is limited to monoliths with straight and parallel channels. However, this format drives to laminar regime flow thus restricting the radial mass and heat transfer. Conversely, AM allows the production of a wider variety of compositions and more complex structures that have proven to rise their effectiveness by increasing reagents‐catalyst interaction, making catalytic processes more cost‐effective. Therefore, in this review an outline of the recent progress of AM methods in the development of monolithic catalysts is presented focusing on the requirements, advantages, and disadvantages of each technique, hence providing a practical overview of their novel opportunities to overcome current limitations in catalyst synthesis.

“…Generally, methanol needs to be reformed before being used in SOFCs, and the main reforming methods include steam reforming, partial oxidation reforming and auto-thermal reforming. Among these methods, methanol steam reforming is the most commonly used method due to its high hydrogen yield and controllability (7)(8)(9). The typical working temperature of SOFCs is 700°C-800°C; thus, if we combine the reforming reactor and SOFC stacks to form a complete system, the temperature of these two parts should match each other to guarantee the coupling degree of the system.…”

Methanol generally needs a steam reforming process before being used in solid oxide fuel cells (SOFCs). This paper calculated and tested the composition of methanol reforming gas under different steam-to-carbon ratio (S/C ratio) and temperature. Results show that when the temperature is between 720°C and 820°C, experiment results are almost consistent with calculation results. When the temperature is around 620°C, a significant deviation exists between the experiment and calculation results, indicating that methanol conversion is incomplete. When the S/C ratio needs to be higher than 1.2 due to the equipment's limit, the appropriate reaction condition is 725°C and S/C ratio of 1.2. Methanol reforming gas under this condition was tested on a commercial SOFC. The peak power is 39.31W under 750°C and 46.97W under 800°C. The highest electrical efficiency reaches 52.4% when fuel utilization is 80%. These results provide a research basis for the future application of methanol in SOFCs.
